The SSL handshake involves several network round trips, with some CPU intensive crypto. I'd expect this to be tens of milliseconds on two local/adjacent machines. To be honest I think 30 seconds would indicate a problem with the setup but appreciate you would have investigated it. But in any case I don't like the implications when a failover takes place.
After handshaking, I anticipate some additional time and CPU for encryption/decryption, plus headaches caused by the network transmission overheads (packet size/segment size mismatches etc). Any additional latency is going to add up with many round trips for a query & resulting data set.
Any one else got some experiences in this area ? Including gotchas/tuning hints seeing as its likely to go ahead !
